There seems to be something not working with OSM, especially for the Roads MapType. In Companion app it seems to work, only showing tile from centre, drag to either side and no tile shows, but with compiled app, tested on 2 devices (A13 & A16) the app starts up showing Roads type one can zoom or drag around, but if one switches to Aerial or Terrain (which seem to be working OK), then back to Roads, Roads is blank (grey hatched background).
(note, I see several Kodular users having similar problems)
